Might Travels posts an offer where getting the basic level of LifeLock can result in a lot of points.
Remember, with deals like these YMMV (your mileage may vary!) so determine what risk level is okay for you.
Since the amount of miles is actually posted, I feel more confident in this than other deals.
Reward mall windfalls can be really nice. I never got on the US Airways Track-it-Back deal where people received six figures of miles, but I did get on the My Points / OpenSky deal windfall and enjoy my various products I got from OpenSky for less than free, after you take the value I got from my points into consideration.
